Signal switch for console and peripheral devices

Abstract

A signal switch for sharing a video monitor, a plurality of console devices compliant with an industry standard and one or more than one peripheral device in any of a plurality of computer systems, is provided comprising a CPU with a first memory for storing a management program for managing the signal switch; a hub switch module connected to the CPU and configured to communicate with any of the plurality of computer systems, and the one or more than one peripheral device; a device control module for emulating according to the industry standard the plurality of console devices, connected to the CPU and the hub switch module; a host control module connected to the CPU and configured to communicate with the plurality of console devices; and a video control module connected to the CPU and configured to communicate with a video monitor device.

1. A signal switch for sharing a video monitor, a plurality of console devices compliant with an industry standard and at least one peripheral device in any of a plurality of computer systems, comprising:
 a CPU comprising a first memory for storing a management program for managing the signal switch; 
 a hub switch module connected to the CPU and configured to communicate with any of the plurality of computer systems, and the at least one peripheral device and any of the plurality of console devices, wherein the management program makes a signal passing from the hub switch module to the at least one peripheral device; and 
 a video control module connected to the CPU and configured to communicate with a video monitor device, 
 wherein the console devices can be switched either synchronously or asynchronously to the same one of the plurality of computer systems or to different ones of the plurality of computer systems, without interruption of the signal to the at least one peripheral device. 
 
   
   
     2. The signal switch of  claim 1 , further comprising an OSD control device connected to the CPU and the video control module. 
   
   
     3. The signal switch of  claim 1 , further comprising a root hub. 
   
   
     4. The signal switch of  claim 1 , wherein the industry standard is the Device Class Definition for Human Interface Devices (HID). 
   
   
     5. A signal switch for sharing a video monitor, a plurality of console devices compliant with an industry standard and at least one peripheral device in any of a plurality of computer systems, comprising:
 a CPU comprising a first memory for storing a management program for managing the signal switch; 
 at least one hub module connected to the CPU and configured to communicate with any of the plurality of computer systems, the at least one peripheral device and the console devices, wherein the management program makes a signal passing from the hub module to the at least one peripheral device to emulate origination from a computer; 
 a control module connected to the hub module and the CPU, wherein the CPU may control the control module to emulate according to the industry standard the plurality of console devices; and 
 a video control module connected to the CPU and configured to communicate with a video monitor device, 
 wherein the console devices can be switched either synchronously or asynchronously to the same one of the plurality of computer systems or to different ones of the plurality of computer systems, without interruption of the signal to the at least one peripheral device. 
 
   
   
     6. The signal switch of  claim 5 , further comprising an OSD control device connected to the CPU and the video control module. 
   
   
     7. The signal switch of  claim 5 , the at least one hub module comprising a root hub. 
   
   
     8. The signal switch of  claim 5 , wherein the industry standard is the Device Class Definition for Human Interface Devices (HID).
